Application Progress of Adaptive Statistical Iterative Reconstruction in Reducing Radiation Dose

As a new CT reconstruction algorithm,adaptive statistical iterative reconstruction(ASIR),could not only reduce radiation dose at body CT,but also provide imaging examples in comparison with low-dose and standard-dose filtered back projection CT.The ASIR reconstruction algorithm is a promising technique for providing diagnostic quality CT images at significantly reduced radiation doses.The development and application of ASIR were reviewed in this article.
